Superhydrophilic carbon nanofiber membrane with a hierarchically macro/meso porous structure for high performance solar steam generators

The utilization of solar energy for water evaporation to obtain fresh water shows potential applications in addressing water scarcity issues. It remains great challenges to develop light absorber materials with high photo-thermal conversion efficiency, large specific surface area and excellent corrosion resistance. Here, we demonstrate a hierarchically mesoporous and superhydrophilic carbon nanofiber membrane (CNF) based on the sublimation of...
